Comment (by azaozz):

 In 40439.4.diff:
 - Take out the (test) UI including the ajax action, etc.
 - Clean up some function and var names, mark the functions non-private,
 add inline docs.
 - Review, improve, account for edge cases in
 `wp_get_missing_image_subsizes()`, `wp_get_defined_image_subsizes()`, and
 `wp_create_image_subsizes()`.
 - Fix the `$duplicate` test when creating new sub-size in both
 `WP_Image_Editor_Imagick` and `WP_Image_Editor_GD`. It only checks whether
 the just resized image matches the source image.
 - Add fallback when a plugin extends `WP_Image_Editor` and doesn't have
 the new `make_subsize()` method that returns the image meta value after
 each sub-size is created.

 There are also some unrelated WPCS fixes in the patch.

 This seems to work well here. Please get the testing plugin and give it a
 go :)
